Xillium

Xillium (also known as Xillium Professional Services) is a specialized clinical support outsourcing (CSO) and healthcare virtual assistant provider serving medical practices, clinics, and healthcare networks across the United States. Founded in 2011 with joint operations in Minneapolis, Minnesota, and Iloilo City, Philippines, Xillium delivers HIPAA-compliant virtual medical assistants, administrative staffing, and operational execution services. The company connects US healthcare providers with trained healthcare graduates and registered nurses who handle complex workflows—including electronic health record (EHR/EMR) management, patient intake and scheduling, insurance verification, medical billing coordination, telehealth assistance, and prescription refills. By integrating offshore remote staff directly into existing clinic administrative operations, Xillium helps enterprise practices reduce overhead costs, prevent provider burnout, and scale clinical capacity efficiently.
